2.1.3 CONNECTING THE POWER SUPPLY
The TI-500 and TI-500E indicators ship standard with an external AC adapter.
1. Simply plug the AC adapter into the indicator’s DC Power Jack first, and then plug
into a standard wall outlet.
Make sure that the AC voltage appearing at the wall
outlet matches the input voltage marked on the AC adapter.
The TI-500-BW alkaline battery indicator ships as a “batteries not included” unit.
1. Obtain six (6) alkaline “C” (UM-2) batteries and install them in the battery compartment
located at the rear of the unit.
Be sure to observe the polarity indicated inside the
battery holder.
The TI-500-BW rechargeable battery indicator ships with the battery pre-installed. The
external power supply (included) can also be used to power the indicator. The adapter for
the rechargeable battery unit acts as the battery charger.
1. Simply plug the AC adapter into the indicator’s DC Power Jack first, and then plug into a
standard wall outlet.
Make sure that the AC voltage appearing at the wall outlet
matches the input voltage marked on the AC adapter.
